How much does a commercial roof replacement cost in Houston?
Commercial roof replacement starts at $20,000, with final cost driven by square footage, deck condition, insulation needs, and how many layers of existing roofing must be removed. A free on-site inspection is the only way to get an accurate figure for your building.
How do I know if my building needs a full replacement instead of a repair?
Leaks appearing in multiple, unrelated areas, wet insulation found during inspection, and repairs that keep recurring in the same sections are all signs the membrane has failed system-wide rather than at an isolated point, which typically means replacement is more cost-effective than continued repair.
Which roofing system is best for a Houston commercial building — TPO, EPDM, or modified bitumen?
The right system depends on your roof’s slope, drainage, and rooftop equipment. TPO offers reflective, heat-resistant surfacing; EPDM performs well on roofs with movement or ponding tolerance; modified bitumen adds redundant, multi-ply waterproofing on low-slope decks. We recommend a specific system after inspecting your deck and drainage.
How long does a commercial roof replacement take?
Timeline depends on square footage and tear-off scope, since both membrane installation and flashing work require dry conditions. Smaller buildings can be completed in under a week; larger commercial roofs may take two to three weeks, with Houston’s rain patterns factored into scheduling.
Can my building stay occupied during a commercial roof replacement?
In most cases, yes. We sequence tear-off and installation in sections and choose application methods — such as cold-adhesive over open-flame torch application — that reduce disruption for occupied buildings, coordinating noisy work windows with your property manager in advance.
What happens to wet or damaged insulation during a replacement?
Saturated insulation is removed and replaced as part of the tear-off, since it won’t dry out on its own in Houston’s humidity and will continue transferring moisture into the building if left in place under new roofing material.
Does a new commercial roof help lower cooling costs?
A reflective membrane, such as white TPO, can reduce rooftop surface temperature compared to an aged, dark membrane, easing the load on rooftop HVAC units during Houston’s long cooling season.
Is a permit required for a commercial roof replacement in Houston?
Commercial roof replacements inside Houston city limits generally require a permit through the City of Houston Permitting Center. We coordinate permitting and confirm wind-uplift requirements referenced in International Code Council standards adopted locally.
What warranty comes with a commercial roof replacement?
Achilles Roofing backs commercial replacements with a 5-year workmanship warranty, which is separate from any manufacturer material warranty on the membrane itself. We review both warranty terms with property owners before work begins.
Can insurance cover a commercial roof replacement after storm damage?
If wind or hail caused the damage, your policy may cover replacement, and we document impact damage with photos formatted to support your claim. Coverage details depend on your specific policy, so we recommend confirming scope with your adjuster before work begins.
Does Achilles Roofing offer financing for commercial roof replacement?
Yes, GreenSky financing is available with payments as low as $199 per month, subject to approval, in addition to a $500 Visa gift card referral program and a $150 discount off replacements for senior, military, veteran, or disabled property owners.
What’s the difference between a roof re-cover and a full tear-off replacement?
A re-cover installs a new membrane over existing roofing that’s still dry and structurally sound, which can lower project cost. A full tear-off removes all existing layers down to the deck and is required when insulation is wet or the deck itself needs repair — a common finding on older Houston commercial roofs.
